Need quick info on Hacker C50 10XL

[captain harlock]

These motors are one of the first sensorless brushless motors to appear in the industry. The Nemesis and Feigao motors are based on them.
They're good, but the LMTs are way better. They're pricy, too. The C50s have a built in heatsink and they seem as big as the 22 series, but a 19 series motor can kick it's a$$ without problem.

Bottomline: if you want to get a Good Feigao, get a Hacker!!!
